CDCA Objective Structured Clinical Examination (OSCE) Practice Exam

A reline of a denture is indicated primarily when there is resorption of the alveolar ridges. Over time, as teeth are lost and the underlying bone and gum tissue begin to change shape or shrink, the fit of the denture can become loose. This can lead to discomfort for the patient as well as a reduction in the effectiveness of the denture for chewing and speaking.

The relining process involves adding material to the tissue-fitting surface of the denture to create a better fit that accommodates these changes in the anatomical structures supporting the denture. This adjustment helps to ensure that the dentures remain functional and comfortable for the patient as their mouth's shape changes over time.

In contrast, situations such as broken dentures or chipped denture bases typically require repairs rather than relining, addressing structural damage rather than fit. Swelling may require a different course of action, which often includes examining the underlying cause of the swelling before proceeding with adjustments to the denture. Thus, relining is specifically warranted in cases where there is a change in the fit due to the resorption of the ridges.
